DESCRIPTION
SiP32401A and SiP32402A are slew rate controlled load
switches designed for 1.1 V to 5.5 V operation.
The devices guarantee low switch on-resistance at 1.2 V
input. They feature a controlled soft-on slew rate of typical
2.5 ms that limits the inrush current for designs of heavy
capacitive load and minimizes the resulting voltage droop at
the power rails.
These devices feature low voltage control logic interface
(On/Off interface) that can interface with low voltage control
signal without extra level shifting circuit. SiP32402A also
integrates an output discharge switch that enables fast
shutdown load discharge.
Both SiP32401A and SiP32402A have exceptionally low
shutdown current and provide reverse blocking to prevent
high current flowing into the power source.
SiP32401A and SiP32402A are in TDFN4 package of 1.2 mm
by 1.6 mm.
